Has anyone tried Selegiline / l-deprenyl ?

wtf?

a small percentage is converted to methamphetamine and amphetamine.

Medical Review Officer interpretation of laboratory results is an important component of drug testing programs. The clinical evaluation of laboratory results to assess the possibility of appropriate medical use of a drug is a task with many different facets, depending on the drug class considered. This intercession prevents the reporting of positive results unless it is apparent that drugs were used illicitly. In addition to the commonly encountered prescribed drugs that yield positive drug testing results, other sources of positive results must be considered. This review describes a series of compounds referred to as "precursor" drugs that are metabolized by the body to amphetamine and/or methamphetamine. These compounds lead to positive results for amphetamines even though neither amphetamine nor methamphetamine were used, a possibility that must be considered in the review of laboratory results. Description of the drugs, their clinical indications, and results seen following administration are provided. This information allows for the informed evaluation of results with regard to the potential involvement of these drugs.

Metabolic transformation of deprenyl enantiomers in rats.Szoko E, Kalasz H, Magyar K.
Department of Pharmacodynamics, Semmelweis University of Medicine, Budapest, Hungary.

The optical isomers of deprenyl have different pharmacological activities and potency. Selegiline, an (-)-isomer, is the more potent monoamine oxidase B enzyme inhibitor, and this substance is used in the therapy of Parkinson's disease. The neuroprotective and neuronal rescue effects of deprenyl, as well as the psychostimulant action of its metabolites, methamphetamine and amphetamine are also different for the enantiomers. In this study the biotransformation of deprenyl enantiomers was compared. Stereoselective dealkylation of both optical isomers was found as major metabolic alteration. The difference in the ratio of the formed metabolites suggests the existence of preferred metabolic pathways for the enantiomers.


the primary metabolite is desmethylselegiline, only small trace amounts are converted to methamphetamine and amphetamine.

Didn't know that about pain meds? I've read that you should be cautious about taking selegiline if you're on anti-depressants (SSRI's, tricyclic, etc.), MAOI's, or sleep aids.... and one should consider an "MAOI diet" if taking higher dosages due to interaction with tyramine in certain foods (cheeses, cured meats, beer, red wine, etc)

What would be a MAOI diet, not very familiar with it myself. Thank you

cheese beer and wine are all high in tyramine, so you want to avoid them

so if you know you're going to be drug-tested, then more than likely they would do this via blood test or urine test, so as long as you stop the selegeline a week or so, then you should be fine? it's the hair test where traces could be detected for several months

would there be any type of side effects over long-term use of deprenyl?

is this as a general precaution when taking selegiline or if you know you're sensitive to this type of interaction? after all, it's not a strong MAOI....if I had to choose between wine/cheese/beer and selegeline, I'd probably not go for the wiser choice

traditional MAOi's can cause this cheese effect, which is a peripheral effect (outside the brain) causing dangerously high blood pressure. however selegiline is very highly selective and at normal dosages only functions as an MAOi within the brain. only at extreme high dosages does selegiline begin to cause the cheese effect. so unless extraordinarily high dosages are being used, and given normal blood pressure to begin with, and no other synergysts or MAOi's are being taken simultaneously - you do not need to worry about watching your diet to avoid the cheese effect with selegiline.
